+
+## Root Cause Analysis
+
+Based on detailed investigation by maintainer @Fank and community reports, the permission issues stem from:
+
+1. **Container Architecture Issues**:
+   - No `USER` directive in Dockerfile despite creating a factorio user
+   - Container starts as root and performs recursive `chown` on every start
+   - The recursive `chown -R factorio:factorio /factorio` can be interrupted, leaving inconsistent permissions
+   - Dynamic UID/GID mapping using PUID/PGID environment variables adds complexity
+
+2. **Rootless Docker Complications**:
+   - UID namespace remapping (e.g., container UID 845 → host UID 100844)
+   - Rootless Docker daemons cannot change ownership of bind-mounted volumes
+   - Different rootless implementations use different UID mappings
+
+3. **Host System Dependencies**:
+   - Older Docker versions (especially pre-20.x) have permission handling bugs
+   - Some kernel versions have issues with user namespace operations
+   - SELinux and AppArmor can interfere with volume permissions
+
+## Critical Prerequisites
+
+### Update Your System First!
+Many permission issues are caused by outdated system components:
+
+```bash
+# For Ubuntu/Debian
+sudo apt-get update
+sudo apt-get upgrade
+
+# Specifically update Docker to 27.x or newer
+# Follow: https://docs.docker.com/engine/install/ubuntu/#install-docker-engine
+```
+
+**Important**: Multiple users reported that updating Docker resolved their "Operation not permitted" errors.
+
+## General Solutions
+
+### Solution A: Pre-create Directories with Correct Permissions
+```bash
+# Create the directory structure
+sudo mkdir -p /opt/factorio/{saves,mods,config,scenarios,script-output}
+
+# Set ownership to factorio user (845:845)
+sudo chown -R 845:845 /opt/factorio
+
+# Set appropriate permissions (note the 'u+rwx' for write access)
+sudo chmod -R u+rwx /opt/factorio
+```
+
+### Solution B: Use the Rootless Docker Image (Recommended)
+The project now provides a rootless variant that runs as UID 1000, which avoids most permission issues:
+```bash
+docker run -d \
+  -p 34197:34197/udp \
+  -p 27015:27015/tcp \
+  -v /opt/factorio:/factorio \
+  --name factorio \
+  factoriotools/factorio:latest-rootless
+```
+
+**Benefits of rootless images**:
+- No `chown` operations on startup
+- No need to pre-create directories with specific permissions
+- Works seamlessly with rootless Docker installations
+- Avoids the recursive permission changes that can be interrupted
+
+**Available rootless tags**:
+- `latest-rootless`
+- `stable-rootless`
+- `2.0.55-rootless` (or any specific version with `-rootless` suffix)
+
+## Platform-Specific Issues and Solutions
+
+### NixOS with Rootless Docker
+
+**Problem**: Permission denied errors when creating directories, even after setting ownership to 845:845. Files show ownership by UID 100844 instead of 845.
+
+**Solutions**:
+1. **Find and use your actual rootless Docker user ID**:
+   ```bash
+   # Method 1: Check your user ID
+   id -u
+   
+   # Method 2: Check existing Docker volumes for the UID Docker is using
+   ls -lan /path/to/other/docker/volumes
+   
+   # Common rootless Docker UIDs:
+   # - 100999 (NixOS default)
+   # - 100844 (as reported in issue #558)
+   # - 1000 (some configurations)
+   
+   # Apply the correct ownership
+   sudo chown -R 100999:100999 ./factorio
+   ```
+
+2. **Configure NixOS Docker properly**:
+   ```nix
+   # In configuration.nix
+   virtualisation.docker.rootless = {
+     enable = true;
+     setSocketVariable = true;
+   };
+   ```
+
+3. **Port Mapping Issues**: Rootless Docker on NixOS has issues with userland-proxy that can cause random port assignments. Consider using host networking if possible.
+
+### macOS with Colima
+
+**Problem**: `copy_file` permission denied errors, even with correct ownership. Permission errors when running docker-dlc.sh.
+
+**Solutions**:
+1. **Set broader permissions before mounting**:
+   ```bash
+   # Create directory structure
+   mkdir -p ./factorio-server/{saves,mods,config,scenarios}
+   
+   # Set ownership AND permissions
+   sudo chown -R 845:845 ./factorio-server
+   sudo chmod -R 775 ./factorio-server
+   ```
+
+2. **Use Docker Desktop instead of Colima** if the issues persist, as it has better macOS integration
+
+3. **Specify PUID/PGID explicitly**:
+   ```yaml
+   environment:
+     - PUID=502  # Common macOS user ID
+     - PGID=20   # Common macOS staff group
+   ```
+
+### Windows
+
+**Problem**: Cannot remove temporary locale files due to Windows-Linux permission translation. Errors like "Permission denied trying to remove /factorio/temp/currently-playing/locale/de".
+
+**Solutions**:
+1. **Use WSL2 backend** for Docker Desktop (required for proper Linux filesystem semantics)
+
+2. **Store volumes in WSL2 filesystem** instead of Windows filesystem:
+   ```bash
+   # Inside WSL2 terminal
+   mkdir -p ~/factorio
+   chmod -R 777 ~/factorio
+   ```
+   
+   ```yaml
+   # docker-compose.yml - use WSL2 path
+   volumes:
+     - ~/factorio:/factorio
+   ```
+
+3. **Avoid Windows drive mounts** (like `W:\docker\factorio`) as they have inherent permission translation issues
+
+4. **Add :Z flag for SELinux context** (some Windows Docker setups benefit from this):
+   ```yaml
+   volumes:
+     - ~/factorio:/factorio:Z
+   ```
+
+### Synology NAS
+
+**Problem**: Permission denied when accessing mounted volumes. Error: "filesystem error: status: Permission denied [/factorio/saves]".
+
+**Solutions**:
+1. **Create and set permissions via SSH**:
+   ```bash
+   # SSH into Synology
+   sudo mkdir -p /volume1/docker/factorio
+   sudo chown -R 845:845 /volume1/docker/factorio
+   sudo chmod -R u+rwx /volume1/docker/factorio  # Important: u+rwx for write access
+   ```
+
+2. **Use the correct volume path in your container**:
+   ```bash
+   docker run -d \
+     -p 34197:34197/udp \
+     -p 27015:27015/tcp \
+     -v /volume1/docker/factorio:/factorio \
+     --name factorio \
+     --restart=always \
+     factoriotools/factorio
+   ```
+
+3. **Check DSM Docker permissions** - ensure the Docker package has proper permissions to the shared folder
+
+## Docker System Requirements
+
+### Minimum Docker Version
+Based on community reports, these Docker versions are known to work:
+- **Docker 27.4.1** - Confirmed working
+- **Docker 20.x+** - Generally stable
+- **Docker 19.x and below** - Known permission issues
+
+**Check your Docker version**:
+```bash
+docker --version
+# If below 20.x, update immediately!
+```
+
+### "Operation not permitted" at Util.cpp:81
+This specific error is often caused by:
+1. **Outdated Docker version** - Update Docker first!
+2. **Outdated kernel** - Run system updates
+3. **Missing kernel capabilities** - Check Docker daemon configuration
+
+## Docker Compose Best Practices
+
+### Basic Configuration
+```yaml
+version: '3'
+services:
+  factorio:
+    image: factoriotools/factorio:stable
+    container_name: factorio
+    ports:
+      - "34197:34197/udp"
+      - "27015:27015/tcp"
+    volumes:
+      - ./factorio:/factorio
+    restart: unless-stopped
+    stdin_open: true  # For interactive console
+    tty: true
+```
+
+### Advanced Configuration for Permission Issues
+```yaml
+version: '3'
+services:
+  factorio:
+    image: factoriotools/factorio:stable
+    container_name: factorio
+    ports:
+      - "34197:34197/udp"
+      - "27015:27015/tcp"
+    volumes:
+      - ./factorio:/factorio:Z  # :Z for SELinux systems
+    restart: unless-stopped
+    # user: "845:845"  # WARNING: This might break the entrypoint script
+    environment:
+      - PUID=845
+      - PGID=845
+      - UPDATE_MODS_ON_START=false  # Disable if having permission issues
+```
+
+### Rootless Docker Configuration
+```yaml
+version: '3'
+services:
+  factorio:
+    image: factoriotools/factorio:latest-rootless
+    container_name: factorio
+    ports:
+      - "34197:34197/udp"
+      - "27015:27015/tcp"
+    volumes:
+      - ./factorio:/factorio
+    restart: unless-stopped
+    environment:
+      - PUID=1000  # Rootless default
+      - PGID=1000
+```
+
+## Advanced Troubleshooting
+
+### Step-by-Step Diagnosis
+
+1. **Check Current Ownership**:
+   ```bash
+   ls -lan ./factorio
+   # Look for UIDs like 845, 1000, 100844, 100999
+   ```
+
+2. **Verify Docker User Mapping**:
+   ```bash
+   # Check what user the container is running as
+   docker exec factorio id
+   
+   # Check file ownership inside container
+   docker exec factorio ls -lan /factorio
+   ```
+
+3. **Test Without Volume Mount** (isolates host permission issues):
+   ```bash
+   docker run --rm -it factoriotools/factorio:stable
+   # If this works, the issue is with your host volume permissions
+   ```
+
+4. **Check Security Modules**:
+   ```bash
+   # SELinux (Fedora, RHEL, CentOS)
+   getenforce
+   # If "Enforcing", try adding :Z to volume mount
+   
+   # AppArmor (Ubuntu, Debian)
+   sudo apparmor_status | grep docker
+   ```
+
+5. **Debug the Entrypoint Script**:
+   ```bash
+   # Run with debug output
+   docker run --rm -it \
+     -e DEBUG=true \
+     -v ./factorio:/factorio \
+     factoriotools/factorio:stable
+   ```
+
+### Common Error Messages and Solutions
+
+| Error | Cause | Solution |
+|-------|-------|----------|
+| `Util.cpp:81: Operation not permitted` | Outdated Docker/kernel | Update Docker and system packages |
+| `chown: Operation not permitted` | Rootless Docker | Use rootless Docker UID for ownership |
+| `Permission denied [/factorio/saves]` | Wrong directory permissions | `chmod -R u+rwx` on host directory |
+| `Couldn't create lock file /factorio/.lock` | Container can't write to volume | Check volume mount and permissions |
+| `Map version X cannot be loaded` | Version mismatch | Use correct Docker image version |
+
+## Known Issues and Limitations
+
+### Interrupted chown Operations
+The container performs `chown -R factorio:factorio /factorio` on every start. If the container is killed during this operation:
+- Files will have inconsistent ownership
+- Some files owned by 845, others by different UIDs
+- Solution: Let the container complete startup before stopping
+
+### Rootless Docker Port Mapping
+**Issue #496**: Rootless Docker with userland-proxy causes random port assignments instead of the configured 34197.
+- **Workaround**: Use host networking mode if possible
+- **Note**: This is a Docker limitation, not specific to this image
+
+### Map Version Compatibility
+**Problem**: "Map version 2.0.23-0 cannot be loaded because it is higher than the game version".
+
+**Solution**: 
+```bash
+# Use a version that matches or exceeds your save
+docker pull factoriotools/factorio:2.0.23
+# Or always use latest for newest features
+docker pull factoriotools/factorio:latest
+```
+
+## Recommended Approach
+
+### For New Installations
+1. **Update your system first** - Many issues are caused by old Docker versions
+2. **Try the rootless image first** - It avoids most permission issues entirely
+3. **Pre-create directories** with correct permissions if using the standard image
+4. **Test without volumes** first to ensure the image works
+
+### For Existing Installations with Issues
+1. **Stop the container** and let it shut down cleanly
+2. **Backup your data** before making changes
+3. **Check Docker version** - update if below 20.x
+4. **Fix permissions** using the platform-specific solution
+5. **Consider rootless variant** for easier permission management
+
+### Best Practices
+- **Let the container start fully** before stopping (avoid interrupted chown)
+- **Use named volumes** instead of bind mounts when possible
+- **Monitor first startup** to ensure permissions are set correctly
+- **Keep Docker updated** to avoid known bugs
+
+## Community Solutions
+
+### Proposed Improvements (from @Fank)
+1. **Add USER directive** in Dockerfile after creating directories
+2. **Optimize chown logic** to only run when ownership is wrong
+3. **Implement fixuid** for better UID/GID mapping
+4. **Add health checks** to ensure permissions are correct before starting
+
+### Alternative Images
+Some users have tried other Factorio Docker images (e.g., goofball222/factorio) but report the same Util.cpp:81 errors, suggesting this is a broader ecosystem issue related to Docker versions and system configurations.
+
+## Quick Reference
+
+| Platform | Common UID | Recommended Approach |
+|----------|-----------|---------------------|
+| Standard Docker | 845 | Update Docker, use `chown 845:845` |
+| Rootless Docker (NixOS) | 100999, 100844 | Find actual UID, chown to that |
+| macOS (Docker Desktop) | 502 (user), 20 (staff) | Use PUID/PGID env vars |
+| Windows | N/A | Use WSL2 filesystem |
+| Synology NAS | varies | Check DSM user, ensure Docker has folder access |
+
+## Getting Help
+
+If these solutions don't work:
+1. **Update everything first** (Docker, kernel, system packages)
+2. **Provide full details** when reporting issues:
+   - Docker version (`docker --version`)
+   - OS and version
+   - Full error messages
+   - Output of `ls -lan` on your volume
+3. **Try the rootless image** as an alternative
+4. **Check issue #558** for ongoing discussions
+
+Remember: The vast majority of permission issues are resolved by updating Docker to version 20.x or newer!
